Abstract : Certain high-altitude nuclear bursts produce abnormal ionization in the atmosphere which can affect radio propagation over a wide area for as long as two weeks after the burst, particularly in the LF and VLF regions. The effects are most pronounced and persistent at night. They have been reported following both the 1958 and 1962 test series, but no theoretical interpretation of them has been given so far. A general semi-quantitative theoretical explanation of the observed effects is presented, which should be of interest to those concerned with theoretical or systems applications of the large variety of effects of nuclear bursts on the lower ionosphere and on radio propagation.
